Agreed, and in particular that last one combined with haptic feedback. It's good to see it's being thought about though, as I am intending to purchase the IXEG 737 and I do fly VR, so I am quite interested in this. Thanks for taking the time to respond.

Whilst that was true, fairly recently it's becoming more of a reality. I use VR in airliners and I know of a Twitch streamer that does too:
The fidelity of the headsets is just about there now (i.e. now that we're past gen 1 VIVE and Rift) and modern systems, with correctly configured X-Plane 11, can achieve decent performance in VR.

There's something on the Org store for shadows, but I don't own it and can't vouch for how effective it is: https://forums.x-plane.org/index.php?/forums/topic/180622-mwp-projects-trueshadows-release/
Shadows don't bother me enough to buy it.
